Hi welcome to The Science Show! Today I will be telling you about Photosynthesis.
There are two parts of photosynthesis the light reaction and the calvin cycle. Right now I will tell you about the light reaction
Photosynthesis occurs in the leaves of a plant, specifically in the thyroid inside the chloroplast.
In the fall plants temporarily stop photosynthesis. The chlorophyll (the stuff that makes leaves green) dies off. That is why the leaves turn other colors and then die.
Now the Calvin Cycle. The purpose of the Calvin Cycle is to convert CO2 into glucose. The Calvin Cycle occurs in the Stroma which is inside of the chloroplast.
In order to make glucose out of the ATP and NADPH from the light reaction the plant needs to go through a process called CO2 Fixation. to do this the plant takes the CO2 from the air and is attached to RUBP creating an unstable six carbon molecule chain that immediately splits into two three molecule chains eventually creating glucose.
The light reaction occurs in the leaves of a plant, specifically in the Thylakoid inside the chloroplast. When the plant absorbs sunlight and water and turns it into energy, or ATP, and NADPH oxygen is released as a waste. Water is split to replace the electrons that are being transported to the next photo system.
